You can use one voltage and use few Amps but only on one phase . If you want to measure Amps on other phases you should add another voltage meter on each phases.
You can't to use transformer for power supply because on transformer for measuring is AC voltage and power supply for arduino is DC voltage

@GambitukI am very happy with performance. I'm logs power every 10s and voltage every 60s. It is sufficient. I built like on this site http://openenergymonitor.org/emon/buildingblocks/measuring-voltage-with-an-acac-power-adapter
You can use transformer what you like but you must add voltage divider to have voltage max 2,5V on input in arduino if you use arduino 5V

PS Poland/Warsaw

I use 3 x transformers One for each phase

In Emonlib you have example to measure watt etc. without measure voltage.

A3 is from transformer and A0 is from CT sensor

CT input http://openenergymonitor.org/emon/buildingblocks/how-to-build-an-arduino-energy-monitor-measuring-current-only

I have 3 x voltage input and 3 x ct input.

I use transformer to measure voltage on each from three phases

Yes and yes. first lever repeater should have id 0. All my nodes have static repeater or gateway id. Now i don't have loops after restart gateway.

I have the same situation. My solution is to add manually repeater id in each node.

In yours sketch state button should high next low then relay change state. I want to have possibility after button HIGH relay state change button LOW state relay change again

Could someone tell what i should to modify to use toggle button not flash button?

Maybe but my node doesn't get any information from gateway

Could someone explain me why on node i have repeater id "8" but in getaway repeater id is "2". I have 9 nodes and it is first that does not work

I use Pidome server and by automation rule send values to emoncms..

@ServiceXp In the box are 3 transformer, one for each phase to measure the voltage

My hardware is on photo. I prepare hardware from emoncms site for 3 phases. My sketh working good so far about 3 weeks. My controler is pidome and send values to emoncms on mys NAS.

I created a power meter based on emoncms. My code does not work quite correctly. When I run not everything is fine, but after reboot gets below the value of information and does not update.

Try to turn off node, restart pidome server. After restart go to drivers management/ drivers.. Turn on node and refresh drivers page. If you see new request about id press apply. You have only few second after power on node to apply new address.

I prepare sketch with 2 x button and 2 x relays and 8 x dallas. Could some one look at if it right, because i have problem remote relays after restart node. I don't know it is problem witch sketch or server software.
